Neutrino Superbeam Scenarios at the Peak

Abstract

We discuss options for U.S. long baseline neutrino experiments using upgraded conventional neutrino beams, assuming $L/E_\nu$ is chosen to be near the peak of the leading oscillation. We find that for L = 1290 km (FNAL-Homestake) or 1770 km (FNAL-Carlsbad, or BNL-Soudan) it is possible to simultaneously have good $\sin^22\theta_{13}$ reach and sgn($\delta m^2_{31}$) determination, and possibly sizeable $\tau$ rates and some $\delta$ sensitivity.
